The 100 Watt Hour Per Day Chest Fridge

Becky and I pay NZ22.3 cents per kilowatt hour for electricity, so reading about this “fridge” was nearly a religious experience for me.

After we get our desperately needed solar hot water system, this will be the next project:

Using vertical doors in refrigeration devices is an act against the Nature of Cold Air. Understanding and cooperating with Nature rather than acting against it leads to much better efficiency.

My chest fridge (Vestfrost freezer turned into a fridge) consumes about 0.1 kWh a day. It works only about 2 minutes per hour. At all other times it is perfectly quiet and consumes no power whatsoever. My wind/solar system batteries and power-sensing inverter simply love it.

    That is something I’ve just got to make. We were going to see if we could organise ourselves to do without a fridge entirely – there is not much in the fridge that really has to be there. But this upsets the apple cart. I’ve now got a choice. Hot diggity.

    When Bex and I first got here, we didn’t have a fridge. We barely managed with a chilly bin (that’s “ice chest” or “cooler” in New Zealaneze, for those of you who don’t know). We now see our conventional fridge as a luxury item. We could probably survive without one, but at what cost? It’s not worth it to get rid of it, even at the criminal prices we’re paying for electricity.

    We would love to build one of these modified freezer fridges.
